SUMMARY 

You'd be hard pressed to find an accessory infused with more passion and personality than 
shoes. Despite this, we're offered an extremely limited number of styles and models. Unless 
you're super rich (unlikely) or a shoemaker (even less likely) you probably haven't 
considered custom footwear. However, making your own shoes may be easier than you

think. 

I'm talking about creating interchangeable uppers that reflect your creative vision, in 
everything from material choice to pattern. By cannibalizing the soles from pre-existing 
footwear, you can make a pair of interchangeable strappy shoes with unlimited styles that 
you can swap out as fashion sees fit. 

When I mention that I make shoes, I often get the same response: "Oh my God, can you 
make me some? I'm a total shoe addict!" And if you're anything like me, you've had fantastic 
visions of creating your own boots, platforms, wingtips... 

But very few of us actually turn these ideas into reality. Making shoes isn't easy. The fact 
that the process is surrounded with an aura of mystery doesn't help either. As a result, 
custom shoes are only available to those with the means to pay a shoemaker over $1 ,000 
per pair. The rest of us must search through a sea of mediocre, mass-produced footwear. 
This needs to change. 

We can start by taking some lessons from open source models of software development. 
How? We're going to cannibalize existing shoes, make them modular, and minimize the risk 
of experimentation. 

We start by cannibalizing the most complicated part of the shoe — the sole. The sole 
provides support and cushioning to the foot's complex structure of bones, joints, muscles, 
and tendons. Since most shoe companies spend quite a bit of time and money working out 
issues of construction, materials, and support, we can benefit from their hard work by using 
existing soles as the platform from which we can build. 

Currently, almost all shoes are constructed by gluing the upper (the part that covers your 
foot) to the soles. Once connected, it's nearly impossible to remove these parts from one 
another without doing damage. 

But if we construct shoes to be modular, then the uppers could be removed from the sole 
without destroying either part. Straps could be swapped as easily as Lego bricks. In the 
open source world, developing code in this way allows software developers to distribute a 
workload in manageable sections. Since the shoe is a complicated object, it will be much 
easier for us to build if we break the object into discrete elements. 

Because the whole is broken into interchangeable parts, failure in one realm doesn't bring 
the whole endeavor down. I experienced this firsthand when I made shoes in the traditional

way. I had measured the foot, drafted patterns, cut final materials, sewn them together, and 
finally glued the upper to the sole. But somewhere in there I made a mistake. When my 
girlfriend tried on the shoes, they were three sizes too big. Mistakes in a modular system 
are far less costly. You simply rebuild the part rather than the whole shoe. 

By letting companies do the hard stuff for us, we can start making custom shoes much 
faster and cheaper than if we had to build the whole object. And because we only need to 
make part of the shoe, we can make custom shoes for less than $20. The pair I built here 
cost less than $15 and I wasn't even cutting corners. 

However, I don't make shoes because it's inexpensive. I do it because I love bringing my 
ideas to life. Building modular shoes makes this process much more enjoyable because it 
allows me to make changes and improve a design even as I'm making the shoe. These 
flexible construction methods should empower you to make daring, shocking, or surprising 
shoes. So start building. Your shoes are waiting.

Shop for a pair of shoes. You can find cheap shoes with good soles at thrift stores. Look 
for shoes with a nice shape and the right type of soles. You'll need a shoe with a leather 
footbed. Most pumps and heels will do. You should feel some resistance when you try to 
bend the shoe with your hands. The shoes I've selected have 3 elements that make them 
ideal: the leather footbed is fairly thick; the sole is at least 1/2" off the ground; and the 
footbed has a slight overhang. The shoe you choose has more of an impact on this project 
than any other decision you make. 

Once you've got your shoes, take a deep breath and start cutting. Remove any part of the 
shoe that sticks up from the sole. I recommend an X-Acto knife. Take your time and make 
multiple passes.

• Since the sole is going to be the base for any variations you make, you'll want to take your 
time as you cut the slots that you'll later run the straps through. 

• Start by noting the location of the elements you just removed. I find that most shoes have 
a way of telling me where they want the straps to be. 

• For these shoes, I used 2 of the holes as endpoints. The slot should be less than IV2" long 
and approximately " wide. Be careful to leave about W between the slot and the edge of 
the sole. Any closer than that and you risk tear-out.

Once you've cut the slot from the top, cut into the side of the sole, just below the footbed. 
Remove the excess material and clean out the passage- way. Repeat this process in the 
other 3 locations. 

There are many ways you can attach the uppers to the soles, but I've found this 
one to be very simple. Cut a slot on each side of the sole, just forward of the ball of 
the foot, on either side of the heel. Sew a loop at the ends of each strap, pass the strap 
through a slot, then insert a pin into the loop. This method allows you to assemble and 
reassemble different looks from the same pair of soles.

• Now that you've prepared the raw sole, you'll want to plan your first shoe. Create a 3D 
sketch by cutting strips of felt and running them through the slots. With this cheaper fabric, 
you can test your patterns and get a feel for the ways in which the straps will cover your 
foot. During this stage, feel free to cut the felt at will, mark it up, and see how it looks. If 
you screw up, cut another strip and do it again. 

• Patterns will vary depending on the shoes you cannibalize, so the felt will help you decide 
how to cut the final materials. Pull the felt through the slots so that it starts to look like the 
final shoe. In this case, I used a last to measure, but a real foot works just as well. If 
you're making shoes for yourself, try to enlist someone to pull the felt tightly around your 
foot while you're standing in the shoes. You can do it on your own, but there's quite a bit of 
Twister involved. Once the felt feels right, have your assistant mark the felt just below the 
sole. 

• Remove the felt from the sole and trim any additional areas. This is your pattern. Make 
sure to account for the allowance you'll need to create the loop in the fabric. Then, mark L 
and R on each side. Be sure to double-check this part. I can't tell you how many times I've 
made 2 lefts. It stops being funny after the first time.

• Lay your material wrong-side up 
and cover it with the felt pattern. 
Use thin fabric and baby powder to 
create a little duster. Dab the 
pattern to lightly coat the felt and 
leather. Then pull up the felt for a 
ghosted pattern. Cut it out with the 
sharp tool of your choice. Repeat 
with the internal material, being 
careful to flip your pattern. This is 
the mirror image of the outside of 
the upper, but it doesn't have the 
loop allowance.

If using fabric, sew everything 
together as you would a garment. 
First fold the loop allowance over, 
leaving enough room for the rod 
(approximately 1/4"). Now sew 
along the edge of the allowance, 
enclosing the loop. Then sew the 
upper and backing together. If 
there's a lot of stretch, you'll need 
to sandwich an extra layer between 
them. 

If using leather, glue the pieces 
with a thin layer of contact cement. 
(Since you can't pin leather, this is 
how you connect it before sewing.) 
Then sew the cemented pieces 
together. If using garment-weight 
leather you may be able to sew it 
on your own machine, but be 
careful. Work up to it by practicing 
on a single layer first. Get a feel for 
how your machine is responding. If 
it's not having trouble, continue, but 
if it's straining, stop sewing. It'll be 
much cheaper to bring the pieces 
to a shoe repair shop or a dry 
cleaner that does tailoring. 

Repair shops have industrial 

sewing machines. Give 

clear instructions and negotiate a 

price. 

You should now have pieces that 
look like the photo at left. Trim off 
the excess backing.

With a fine-tooth saw or Dremel tool, cut your rod or dowel to make the pins. Because of 
the sole flex, try keeping the pin under 2"; I find IV2" or smaller is ideal. The pin should be 
about "-W longer than the groove you've cut into the sole. This overlap keeps your 
strap from coming out. Once you have the correct length, sand the ends of the wood or 
acrylic to remove any sharp edges. 

I suggest using an acrylic rod since it's light and easy to cut, and it slides through 
material easily. With that said, I used wood dowels for this project, because they 
were easier to find. 

Slip the end of the strap through the slot in the front of the shoe. Once it's through, slide 
the pin into the end of the strap and pull the strap so the pin is snug against the sole. Now 
connect the other side of the front strap and do the same at the heel.
